  • 1947: After accidentally corrupting a Gnomon algorithm configuration file, The United States Army Signal Corps uses the Project Diana antenna to extract high-grade Clandestiphrine from the corruption stream. APTO field engineers will quickly disambiguate the corruption, but an undisclosed volume of Clandestiphrine remains under Army control.
